How does mean parameter in rnorm function works

Question

I was wanting to know how does the mean parameter in rnorm function work? Because, when I pass rnorm(n = 2, mean = 2), it does fetch me two random numbers (which is understood) but, I'm not sure about the significance of mean value which we're passing as the second parameter. The output is 2 random numbers but, the mean is never 2.
